Original No. 1,602,875, dated October 12, 1926, Serial No. 680,825,fi1ed Deeember 15, 1 923. Application ior reissue filed November 14,1927. Serial No. 233,288.

My invention relates to suction rolls for paper making machines.

One of the objects of the invention is to provide a simple, practicaland advantageous construction of suction roll and suc tioncon'ipartn'lent or chamber therefor.

Another object of the invention is to, simplify the constructionof theroll and the suction chamber and the cooperating and associated partsand mechanisms.

Another object of the invention is to avoid the use of driving gears andsecure direct driving of the roll as in the case of ordinary plain rollsin paper machines.

Another object of the invention is to provide new and improved mechanismfor 00- operating with the suctlon roll and the suction chamber thereinand permitting and adapted for the direct drive of the suction roll.

Another object of the invention is to provide simple and practicalmechanism for permitting the withdrawal or removal of the suctionchamber from within the suction roll, and also for permitting theremoval ofa wire from the roll and replacement of another one thereon.

In the accompanying drawings Figure 1 is a longitudinal section of anend portion of a suction roll and suction chamber embodying my presentinvention.

Figure 2 is a similar longitudinal section of the opposite end of theroll and chamher.

Figure 3 is a view of the end of the device shown in Figure 1.

Figures 4, 5 and 6 are cross sections taken on lines IVIV, VV and VIVI,respectively, in Figure 2.

Figures 7, 8, 9 and 10 are views of a coupling for connection with thesuction roll for driving the same.

Referring to the drawings, I show a suction roll embodying a cylindricalportion 1 which is provided with apertures 22. This cylindric member ismounted to rotate and to such end is provided atone endwith ahead 3having a cylindric or journal portion 4, and at the other end withanother head 5 having a cylindric bearing or journal portion 6 which ispreferably provided with a tapering extension 7 terminating in a reduced cylindrfic portion 8. The heads .3 and 5 are preferably secureddetachably to the and the head 5 by bolts head 3, said member 11 beingconfined within and supported by a bearing conveniently consisting of anupper member 12 and a lower member 13, which are held :together by bolts14-14., which latter may be so tightened as to clamp the members 12 and13 together and thereby hold the cylindric member 11 firmly in astationary condition. A collar or sleeve 15 of suitable bearing metal ispreferably interposed between the cylindric portion 4 and the member 11to permit rotation and takeup Wear.

The bearing 12, 13 is conveniently mounted on a pedestal 16 which inturn is mounted on a foundation or floor 17. The pedestal 16 has achamber 18, the upper end of which' communicates with the interior 19 ofthe cylindric portion ll'through an opening 20 m the member 11, and saidchamber 18 also communicates with a suction pipe 21 whereby a conditionof suction or reduced air pressure may be provided in the interior ofmember 11. v

The member 11 is preferably the end portion of a suction chamber 22which extends lengthwise through the suction roll and whose other end isprovided with acylindric portion 23'which forms the bearing for therotary roll end 6, asleeve 24 of suitable bearing meta-l beingpreferablyinterposed between trunnion 23 and bearing 6. Thus the suction rollcontains and revolves about the suction compartment or chamber 22 whoseends 'form fixed shaft sections or trunnions for the cylindric ends orbearings of the suction roll.- v

The rotary end 6 of the suction roll is mounted in a bearingconveniently comprising a bearing member 25 containing a sleeve 26 ofsuitable bearing material, in which the member 23 rests and rotates(Figs. 2 and 6). A ca 27 is fitted upon the bearing member 25, eingpreferably secured thereto by screws 28. This bearing is oiled,preferably by means of an oil pipe 30, which extends from some source ofoil supply into and along the interior of the suction chamber and hasits end ill connected to the member :22 and in communication with anopening therein leading to the bearing metal sleeve 24, said oil pipehaving a branch )ipe 30 for oiling the member 11 in bearing s eeve 15.Oil chambers 3333 and oil ducts 34 and 35 are provided for oiling theoutside of the rotary end 6 and oil ducts 3737 with an oil chamber 38are provided for conveying oil to this hearing, an annular oil partition40 being rovided to prevent the escape of oil into the Interior of thesuction roll. A ring 41 is mounted on the cylindric member 6 andprovided with a wiper 42 in position in a recess 43 in the cap 27.

The bearing member is mounted on a pedestal 44 and a rocking hearing isprct'crably provided, as by making the lower surface 46 of said bearing25 of circular form and providing a correspondingly curved seat 47 so asto permit a moderate amount of swin ing or tilting motion on the part ofthe mem r 6, and therefore on the part of the suction roll, such motionbeing vlimited by a pin 48.

The reduced end 8 of the member 6 is extended through an aperture 49 inanother pedestal 50 and this end 8 is subject to the action of anadjusting screw 51 carrying an end nut 52 bearing on the end 8 so thatby screwing the screw 51 down'pressure will be exerted on portion 8 andthereby cause said portion 8 to' be depressed and consequently elevatingthe opposite end '11 of the suction roll about the curved bearing seat46, the

se of which will be described later on. 9 end 8 is also preferablyprovided with a coupling by which it may be driven from a suitablesource of power, and this coupling is preferably of such nature as totake up the adjustment of the member 8'above referred to. Thiscouplingis shown in Figure 2 and also in Figures 7 to 10 inclusive, andmay consist of separate members 53, 54 and 55, whereof member 53issplined or otherwise secured to member 8, and member 54 has a slidingconnection with member 53, and member 55 a crosswise sliding connectionwith 53, and member 55 has a sliding crosswise connection with member54. hlemher 55 is understood to be splined or otherwise secured to, arotary shaft 56 extending to a suitable source of power.

The suction chamber 22 is arran ed so that its upper portion may beadjusted relativcly to the inside of the suction roll cylinder 1 so asto secure a tight contact therewith. and provision is made for varyingthis adjustmentin accordance with circumstances and variousrequirements, and also a deckel arran meat rsfipreferablv provided foraccomm, at ngdl erent widths of paper,

As a preferred arrangement the suction chamber 22 is provided with anupper member 60 mounted on springlike members 6l61, so that said member60 may have a vertical adjustment relative to the cylindric member 1.Small plates 61.are arranged at'the ends of the suction chamber to keepit air tight.

These plates preferably of flexible material more or less of the rollapertures 2.2, and so F accommodate the roll for difi'erent Widths ofpaper.

The slides 64 and 65 are connected by pins 66 with the brackets 67 inturn pivoted at 68 to collars 69 and 70. whereof the collar 69 ismounted on a tubular rod 71 and the collar 70 on a rod 72 containedwithin and arranged to slide relatively to the rod 71. These rods 71 and72 extend out through the left hand end of the suction chamber and areprovided the rod 71 with a rotary adjusting wheel 73, and the rod 72with an adjusting wheel 74, whereby either one or both of these wheels73 and 74 may beturned so as to adjust the brushes 6363 in the mannerand for the purpose above set forth. a

In order to adjust the u )per portion of the suction chamber "ertica yto secure and maintain an air tightconnection with the suction roll, arod 75 is extended longitude nally within the suction chamber andconnected by pins 76 with swinging levers 77 which are pivoted at 78 onfixed brackets 7 9, the upper ends of said levers 7 7 being inengagement with the upper suction roll member 60 preferably through the,medium of adjusting screws 80 which permit adjustment so that all ofsaid levers may be similarl v arranged for movement of the upper portionor part of the suction roll. The rod 75 extends preferabl through theleft hand end of the suction chamber and is provided with a spring 82subjecting it to pressure tending to move it to the left, referring toFigure 1, and thereby cause the levers 77 to exert an upward pressure onthe upper portion of the suction chamber, to cause a tight joint betweenthe sal'ne and the interior'surface of the suction'roll. Rod 75 isprovided with a threaded end 84 on which is mounted a nut 85 to permitadjustment of tension of spring 82 and thereby cause desired variationsin the pressure of the suction chamber upon the suction roll. It will beseen that this adjustment of the suction chamb m y be made as desired bythe mechanical means provided and may be independent of the suctionpressure within the suction chamber.

As a matter of further improvement in the mounting of the roll, thebearing block 13 is mounted on the pedestal 16 in such a manner thatsaid block 13 may be lifted slightly above the pedestal 16 and thelatter is provided with a side extension 87 (Figure 3), which is pivotedby bolt 88 to the foundation member 17 so that said member 16 may beswung out from under the member 13. This is done in order to permitchanging of a wire, themember 16 being moved out from under member 13 topermit the wire to be slid over and around the suction roll. The liftingof the member 13 to permit member 16 to be swung out into sidewiseposition, as indicated in dotted lines in Figure 3, may be accomplishedby actuating screwol so as to depressthe contracted roll end 8, thedepressing of this end tilting the other end of the roll upward, andthcreb'y lifting the member 13 slightly.

As a matter of still further in'iprovement the suction chamber ispreferably provided with wheels or rollers 90 (Figure 2) convenientlysecured to the under side of said chamber and adapted to roll on theunder portion of the cylindric member 1, whereby the suction chamber maybe removed from the suction roll for purposes of repair or replacement,when this takes place the axle or trunnion end 23 simply being withdrawnfrom within the roll end 6, and when the suction chamber is replaced thetapering end of the member 23 permits the proper fitting together of theparts. The roll or wheel 90 is preferably mounted so that it will normaly be slightly above the roll surface, thereby permitting rotation ofthe latter without any interference by said wheel 90. 7

It will be seen that the construction pcr mits a direct drive of thesuction roll through the medium of the drive connection 53, 54 and 55,or through the medium of other connections or couplings as it may bedesired to use. This dispenses with intermediate gears and simplifiesand cheapens construction, as well as yielding the well known advantagesof direct drive.
